As Jim stated it's a P14 Target rifle modified/built by BSA for Parker Hale. Generally the barrels were replaced with a "ball burnished" target barrel to improve accuracy. Parker Hale 5B rear target sight and target swivel added. Safety is correct, as is the bolt handle and it's build on the best of P14 actions "Winchester". Do you have the rifle's provenance - keeper for sure!!!!!
